I am a commercial painting contractor and have a customer who is installing a stainless steel tank that will contain a hot alkali solution. The process will be run at about 98ºC. I am looking for a coating to stand up to a hot caustic solution at a 50 percent concentration.

A. Properly formulated paints based on silicone, dicyandiamide-cured epoxy or fluorocarbon resins should meet these requirements. I suggest you contact your paint salesman for a product recommendation or go directly to the industrial sales department of any major paint company and ask for a product recommendation.
